The following communication was sent to elected representatives of the States of Ohio, Kentucky and Indiana by the President and Chief Executive Officer of Cincinnati Bell Leigh R. Fox on July 10, 2017:

Dear Madam/Sir,

I want to be one of the first ones to inform you that today, Cincinnati Bell announced that it has entered into definitive agreements to combine with Hawaiian Telcom, Hawai’i’s fiber-centric Technology Leader providing voice, video, broadband, data center, and cloud solutions, and to acquire OnX, a technology services and solutions provider in North America and the United Kingdom. These transactions advance Cincinnati Bell’s strategy to focus on two areas of our business that are of significant importance to our customers: network communications and enterprise IT services.

In our Network Communications business, we are focused on the future by migrating both urban and non-urban areas from legacy copper to more advanced, more sophisticated, high-speed fiber broadband offerings. The combination with Hawaiian Telecom complements this strategy by not only providing access to a fiber-rich city in Honolulu, but also to the growing neighbor islands. We will be joining forces with a company with a complementary culture, and critically, a shared commitment to the local areas in which we operate. In addition, Hawaiian Telecom provides us access to the SEA-US trans-pacific fiber cable, providing Cincinnati Bell with access to tech-savvy, data-hungry populations on both sides of the Pacific.

The acquisition of OnX, on the other hand, provides our IT Services business with financial and operational scale and a diversified customer base. Most critically for our clients, it also significantly enhances our offering in of cloud services, infrastructure and cybersecurity – major growth areas for our company and critical service lines for our customers. By expanding our IT Services footprint to include 20+ IT sales offices and 50+ data centers through strategic partners, we will be positioned as a better provider for our existing customers and will be poised to serve new customers by offering end-to-end services in 49 states.

Taken together, these transactions underpin our efforts to build two distinct, but complementary businesses with the appropriate scale, structure and leadership to deliver superior service to our customers and expanded opportunities for our employees.

While today’s announcements will open up new horizons for Cincinnati Bell, they are not changing our core identity. We will maintain the same rigorous approach to customer service and the same connections to our communities that have defined our company for more than a century. As we move forward through this process, I am making a personal commitment to transparency, open communication and engagement. Our eyes are looking to the future, but our roots remain the same.

Today is truly a historic day in this history of Cincinnati Bell. Thank you for your continued partnership and I look forward to a bright future for Cincinnati Bell.

Thank you,

/s/ Leigh Fox

Cincinnati Bell Corporation
